Case 580D Backhoe Loader Service Manual 1981 (P/N 9-69270)

• Machine coverage: Covers the J I Case 580D tractor-loader-backhoe, with factory sections for the naturally aspirated and turbocharged 207 diesel configurations, two- and four-wheel-drive front axles, ROPS cab and canopy equipment, loader, backhoe, and optional three-point hitch. Certain shared diagnosis and tune-up chapters are written for both 188 and 207 diesels; the 580D specification and overhaul material centers on the 207.
• Engine repair sections run from symptom diagnosis and tune-up through engine removal, internal inspection, overhaul, reassembly, adjustment, and run-in. Major work includes the cylinder head and valve train, camshaft and gear train, cylinder block and sleeves, pistons and connecting rods, crankshaft and main bearings, flywheel and oil seals, oil pump, cooling and lubrication systems, Roosa Master DB fuel-injection equipment, and turbocharger service.
• Powertrain coverage includes power-shuttle pressure testing and troubleshooting, torque-converter and clutch service, control linkage, transaxle removal, differential-lock repair, four-wheel-drive transfer gearbox work, drive shafts, wheels and tires, and separate transaxle and self-adjusting brake sections for naturally aspirated and turbocharged machines.
• Hydraulic repair material covers system maintenance, contamination diagnosis and portable filtration, pump testing, Parker Hannifin and Hydreco loader control valves, backhoe and stabilizer valves, steering relief and unloading valves, quick-disconnect couplings, three-point-hitch hydraulics, the boom-lock system, and cylinder disassembly, inspection, resealing, bushing replacement, and installation.
• Electrical, steering, air-conditioning, loader, backhoe, ROPS, seat, and noise-control sections provide system checks, component repair, adjustment, removal and installation procedures, and the related factory specifications.
• Document identity: a 1,726-page PDF compiled from factory sections. Core sheets are marked 9-69270 and dated January 1981; later material includes 9-69271 and 9-69272 revisions through August 1983, while the starter and alternator sections carry 9-69720. The manual includes component-specific torque tables, hydraulic and electrical test data, fluid capacities, wear limits, clearances, and special-tool references.

Coverage and Build Differences

This is a full-machine service manual, not an engine-only specification book. The naturally aspirated and turbocharged 207 builds receive separate detailed specification chapters, and the drivetrain material separates transaxle, differential-lock, and brake repair by engine configuration. Other variant-specific sections distinguish Parker Hannifin and Hydreco loader valves, standard machines from Super D backhoe-control layouts, early and late swing-cylinder circuits, backhoes with or without the optional three-point hitch, and bucket-cylinder arrangements for the extendable dipper. Those differences help prevent parts or procedures from being selected for the wrong build.

Factory Procedures and Diagnostic Depth

Engine diagnosis is organized by symptoms such as hard starting or no-start, misfire, knock, overheating, power loss, excessive oil consumption, and low oil pressure. The tune-up procedures cover top-dead-center location, valve adjustment, injector removal and spray-pattern testing, compression checks, injection-pump timing, governed-speed adjustment, and final checks. A separate stall-test section divides torque-converter and hydraulic stall testing and explains how the results point toward engine, power-shuttle, or hydraulic faults.

The drivetrain chapters go well beyond removal notes. They cover power-shuttle pressure-gauge tests, control-valve service, charging-pump and clutch work, torque-converter disassembly, transaxle gear and shaft service, differential bearing preload, and ring-and-pinion backlash. Hydraulic diagnosis includes individual loader, backhoe, and steering output or leakage tests, relief-valve checks, control-valve disassembly and reassembly, cylinder inspection, and contamination cleanup with the portable filter.

Air-conditioning coverage includes no-cooling, insufficient-cooling, erratic-cooling, and system-noise charts, followed by pressure/temperature checks and service for the compressor, clutch, shaft seal, valve plate, expansion valve, evaporator, condenser, receiver-drier, and ROPS-cab lines.

Illustrations, Schematics, and Service Tools

Representative factory visuals include the engine diagnosis chart, standard-canopy and cab/air-conditioner wiring diagrams, the basic chassis wiring diagram, loader-backhoe steering circuits, four-wheel-drive front-axle exploded views, power-shuttle and torque-converter assembly views, and oil-flow section drawings for the loader and backhoe control valves. Special-tool callouts include the CAS-1153 flex-plate alignment tool, M20624 valve-seal installer, M20615 valve-guide cutter, A43278 injector removal tool, A43277 injector-bore cleaner, and CAS-1617 turbocharger seal tool.

The manual also flags details that can make or break a repair. The Teflon valve-seal procedure uses a protective cap so the valve-stem grooves do not cut the new seal, while the turbocharger section requires oil priming after installation or extended storage to prevent a dry-start failure.

Raised loader and backhoe structures, stored hydraulic pressure, heavy powertrain assemblies, rotating engine parts, and refrigerant require correct blocking, pressure release, lifting equipment, and system isolation. Use the complete factory section and its safety notes before beginning any repair or adjustment.
